<H2>Description</H2>

   Write the problem which corresponds to Handle to a file. The set of
   supported formats depends on the actual external solver which is used.
   All solvers support the mps format. Some solvers on some operating
   system platforms may change or append a suffix to the filename.  Note
   that the mps format does not specify the sense (min or max) of the
   objective function. Note also that any active cutpool constraints in the
   problem will be included in the dump, even though they could be left out
   of the problem that the external solver actually solves.
